Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.popularex.com/ii.-popularity-game/how-to-play/registration.md). # Registration To enter the game, you need to register on the [POPXChain](https://popxchain.org) blockchain. Registration is done through the decentralized POPXWallet, which also serves as user authentication. During registration, each user receives a unique IDNFT token, which contains the user's account information, nickname, avatar, etc. The wallet stores blockchain coins as well as any tokens acquired by the user. In addition to the Populárex dApp, the wallet can be used for authentication and payments in any other blockchain dApps. To launch new ToPs, participate in upvoting, and express their opinions, users need to acquire the native coin of the [POPXChain](https://popxchain.org) blockchain. It can be acquired through the wallet on the [POPXChain](https://popxchain.org) website or through any dApp that operates on the blockchain. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.popularex.com/ii.-popularity-game/how-to-play/registration.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
